Thomas Edison s bright idea
Thomas Edison s bright idea
On January 27, 1880, Thomas Edison received a patent for an electric lamp using "a carbon filament or strip coiled and connected to platina contact wires." This wasn"t exactly the first light bulb, but it was the first practical and inexpensive one, a key technological innovation that introduced a new era. To mark the day, we"re looking at the bright lights of New York City and its surrounding area, as seen from the International Space Station.Desktop Version
It s Republic Day in India
It s Republic Day in India
For India"s 70th Republic Day, we"re featuring an uncommon view of the Taj Mahal in Agra. It"s on this day that India celebrates its official beginning as an independent democratic republic after having endured nearly a century of British rule. Republic Day events include presentations of the Padma Awards (national service honors), a Republic Day parade in New Delhi, and other ceremonies.Desktop Version
Happy New Year! (Again!)
Happy New Year! (Again!)
For the first day of the Chinese New Year, we’re showing the southern fortification of the Xi"an City Wall as it was decorated and lit up for last year"s lunar new year party. The south gate was rebuilt in 2014 and is often used to stage the fireworks show that rings in the Chinese New Year, which falls between late January and early February. Why a different new year celebration date? It comes down to the sun versus the moon: While the widely used Gregorian calendar is based on the Earth"s rotation around the sun, the lunar calendar is marked by the phases of the moon. So, the Gregorian new year always falls on January 1, while the lunar new year date moves around from year to year. Either way, we"re excited to have another excuse to throw a party.Desktop Version
Sunlight sets Iceland s Eyjafjallajökull aglow
Sunlight sets Iceland s Eyjafjallajökull aglow
This is the sun-soaked ice cap of Iceland"s Eyjafjallajökull. Remember the name? It"s that unpronounceable volcano that made you miss your connecting flight back in 2010. That eruption and the vast ash cloud it belched over the North Atlantic was the biggest disruption to air traffic since World War II. And this relatively small but volatile island may yet waylay the world again: Eyjafjallajökull is a lightweight among the 32 active volcanic systems dotting the Land of Fire and Ice—its much larger neighbor Katla has been closely monitored since the 2010 incident.Desktop Version
Across the great plains of Africa
Across the great plains of Africa
This time of year, from late January to early March, babies arrive on the Serengeti. At the height of the wildebeest calving season, thousands of calves are born every day. Moments after birth, these youngsters can walk, and in just a few days, they"ll be able to run fast enough to keep up with the herd. That"s a good thing. Calving season isn"t just a draw for safari tourists wanting a front row seat at the start of the circle of life, but also for predators like lions, cheetahs, and hyenas on the hunt for easy prey.Desktop Version

A horse of many colors
Whitehorse, Yukon"s only city and the largest in northern Canada, will have just seven hours of daylight today, but nature has a way of compensating for this injustice. The area enjoys frequent and spectacular light shows, thanks to the aurora borealis. The mechanics of northern lights are still not fully understood, but scientists agree that solar winds—big pulses of energy from our sun—pass through the Earth"s magnetic fields, especially at the polar regions, resulting in shimmering colors.Desktop Version
Observing a squirrelly day
Observing a squirrelly day
January 21 is Squirrel Appreciation Day. Really. It was established by Christy Hargrove, a wildlife rehabilitator from North Carolina, to draw attention to the importance of these remarkably widespread creatures. Native to five continents and currently living on six (there"s no Antarctic squirrel), there are about 285 species of squirrels in the world, ranging from the tiny African pygmy squirrel to the Bhutan giant flying squirrel (when in Bhutan, be ready to duck).Desktop Version
A march toward a dream
A march toward a dream
For Martin Luther King Jr. Day, we"re going back to August 28, 1963, to the March on Washington. Among those in the front line of demonstrators are baseball great Jackie Robinson and bus-boycott activist Rosa Parks, both towering figures in the civil rights movement. Later this day, the Reverend Martin Luther King Jr. would deliver his "I Have a Dream" speech in front of a quarter-million protesters packed onto the National Mall. The speech is considered among the best in American history and a defining moment in the fight for civil rights. King was just 34 years old.Desktop Version
Ready. Set. Snow.
Ready. Set. Snow.
Far above the clouds, an adrenaline-seeking skier glides past the jagged Crater Rock on Oregon"s Mount Hood. He"s practicing a relatively young sport known as speed riding—similar to paragliding but with more emphasis on high velocity than altitude. Skiers with parachute-like "wings" launch downslope at high speed, navigating runs partly on skis and partly in the air.Desktop Version
Sands of time
Sands of time
At a quick glance, you might mistake these dunes for massive snowdrifts. Although they do make for great sledding, the tiny crystals that form the dunes at White Sands National Park are not snow or ice but gypsum, a soft mineral often used to make plaster and chalk. The dune field became a national monument on this day in 1933 with a proclamation by President Herbert Hoover, which set aside nearly 150,000 acres for preservation. Recently, on December 20, 2019, President Trump signed legislation making it the 62nd designated national park in the National Park System.Desktop Version
A seabird gets schooled
A seabird gets schooled
This deep-diving Brandt"s cormorant appears to be on the hunt for a meal, and there"s plenty of Pacific chub mackerel to choose from here off the coast of Los Angeles, California. While seabirds like the cormorant are a threat to these fish, the mackerel aren"t exactly defenseless. Fish have many unique means of defense, such as traveling in dense schools like this one. It"s a technique that not only allows for speedy travel (because it reduces friction on most of the fish in the school)—schooling also makes it more difficult for predators to pick out an individual victim. For these fish, there"s safety in numbers. But when all else fails, they can take some advice from Dory in "Finding Nemo"—"Just keep swimming, just keep swimming."Desktop Version
In the valley of the doll
In the valley of the doll
Today we"re featuring a picture-postcard view of Val Gardena, a valley nestled in the Dolomites in the South Tyrol region of Italy. This time of year, the remote area may be a bit busier than usual as skiers are drawn to its famous slopes. In summer, it"s known for other outdoor activities, such as rock climbing and hiking. Since the 17th century, the villagers have been famed for their wood carving. Artisans create everything from simple, utilitarian items, like bowls, to finely detailed figurines. One of the woodcarvers" biggest hits? A wooden peg doll that was popular across Europe and the US during the 19th century.Desktop Version

Harvest season begins
Today we"re in Kathmandu, Nepal, where the Boudhanath stupa stands out against the skyline. A UNESCO World Heritage site, the stupa is on the ancient trade route from Tibet—traders have rested and offered prayers here for centuries. Like all stupas, Boudhanath is a mound-like structure containing relics. It was first built sometime after the 600s, when Buddhism was first spreading through Tibet and Nepal. It"s long been a major pilgrimage site for Buddhists, and is said to entomb the remains of Kassapa Buddha, one of the 29 named ancient Buddhas.Desktop Version
Going head-to-head with winter
Going head-to-head with winter
Muskoxen are built to chill. These animals can endure, even thrive, in some of the harshest conditions on Earth—the Arctic winter. Their long, wiry outer coat covers a soft and thick inner layer, called qiviut, that keeps them toasty even as temperatures plummet. When winter ends, the muskoxen shed this undercoat, which is collected and spun into yarn that"s warmer than sheep"s wool and softer than cashmere—pricier, too.Desktop Version
Welcome to California
Welcome to California
These are the peaks of Mount Diablo, part of the Diablo Range in the eastern part of the San Francisco Bay Area. On a clear day, you can see all the way to the Sierras from here. In fact, this is one of the best viewsheds in the Bay Area, which is a feat, since the peaks are comparatively low for the region. While Mount Diablo may tempt you to take in the scenery or hike in the surrounding state park, the area offers compelling stories from American history as well.Desktop Version

The Zugspitze: Germany s highest point
Welcome to the snowy Bavarian Alps, where the mountain called the Zugspitze (TSOOG-shpit-seh) casts a cold shadow over the Eibsee, a small and serene alpine lake. Situated on the border with Austria, the peak is Germany"s highest point at almost 10,000 feet above sea level, towering over the lakeside village of Grainau.Desktop Version
Who s wearing such cute hats?
Who s wearing such cute hats?
The stone figures lining the steps in today"s photo are among 500 rakan statues on the small island of Miyajima in Japan. The colorful knitted caps they"re wearing are offerings from people visiting the island, a tradition followed in other areas of Japan as well. Some believe this gift-giving is based on a children"s folk story of an elderly hatmaker who was unable to make it to market on a snowy day, so he placed his collection of hats on rakan statues to keep their bare heads dry. Later, the statues showed their appreciation by delivering gifts to the hatmaker and his wife so they could celebrate the new year properly. The statues in this photo were individually carved sometime between the 1780s to the 1820s, and no two are alike. They line the path at the base of Mount Misen that leads to the Daisho-in Temple, one of the many temples and shrines on the island.Desktop Version

League of Nations, 100 years later
For the anniversary of the League of Nations, we"re in Geneva, Switzerland, at the Palace of Nations. The LN was founded on January 10, 1920, after World War I. It served as an international diplomatic organization until World War II, when it gradually lost support and was eventually replaced by the United Nations. The Palace, built to be the LN"s headquarters, has served as UN headquarters in Geneva and hosts diplomats for thousands of meetings every year.Desktop Version
Into the woods
Into the woods
On this day in 1908, President Theodore Roosevelt declared 554 acres in Marin County, California, a national monument. William and Elizabeth Kent, who donated the land, insisted the monument be named after naturalist John Muir, the environmentalist known as the "father of the national parks." Part of the Golden Gate National Recreation Area, Muir Woods is best known for its old-growth coastal redwood forests, which make up more than half its land. The redwoods in the monument are 600-800 years old, on average, with the oldest being at least 1,200. The tallest tree is about 258 feet, though redwoods grow as high as 379 feet farther north. Redwoods are an important part of the forest ecosystem. They absorb and "strip" moisture from fog, which then drips into the ground, supporting the trees as well as other forest life.Desktop Version
Take the stairs
Take the stairs
If you want to celebrate Take the Stairs Day in style, look no further than China"s Tianmen Mountain (literally Heaven"s Door). About 5,000 feet above sea level, the hole in the mountain is the highest naturally formed arch in the world. Originally a cave, it became an arch in 263 CE when the back side of the mountain collapsed, creating the dramatic opening we see today. You"ll have to climb 999 steps to make it to the top, but we promise the view is worth it.Desktop Version
Jupiter and the Galilean moons
Jupiter and the Galilean moons
On January 7, 1610, Galileo was the first person to train a telescope on Jupiter—and what he saw surprised him. Strung in a line beside the planet were three tiny stars, one to the left of the planet and two to the right. But when he observed the formation the next night, he saw that now all three were on the same side of Jupiter. Over the following week, he watched as the tiny stars (now joined by a fourth) changed their position relative to the planet while remaining beside it. By January 15, he had it figured out: he was observing four moons orbiting Jupiter.Desktop Version
Have fun storming the castle
Have fun storming the castle
Our headline quote comes from "The Princess Bride" film, of course, but our homepage castle is found in Lithuania, the largest of the three Baltic states (the others are Latvia and Estonia). Construction on this fortress was begun in the 14th century by the Grand Duke of Lithuania and completed years later by his son. It served as a strategic and bustling center of the Grand Duchy of Lithuania, a European state that lasted until 1795. Like much architecture from so long ago, the castle was damaged and fell into disrepair, only to be reconstructed and reopened as a museum. These days it"s known as one of the most charming medieval castles in Europe.Desktop Version
Digging the birds
Digging the birds
Burrowing parrots, sometimes called burrowing parakeets, are native to the arid Monte Desert of western Argentina. The birds use their beaks and talons to hollow out nesting spaces in soft limestone cliffs found in the foothills of the Andes Mountains. The parrots sometimes end up captured and sold as pets for the wild bird trade. While that"s not illegal—burrowing parrots aren"t endangered—the capture and sale of these birds and others is part of the focus of National Bird Day in the United States, which is observed on January 5. National Bird Day was created to educate the public about the value of wild birds remaining wild. While keeping a parrot as a pet may seem like fun, the organizers of National Bird Day claim the parrot is going to be healthier and happier in its natural habitat.Desktop Version
Celebrating whales—and a whale of a tale
Celebrating whales—and a whale of a tale
A mother sperm whale surfaces in the North Atlantic as her young albino calf swims beside her. It"s an especially photogenic moment for these underwater powerhouses, which spend much of their time in the dim depths over 1,000 feet below the waves. You"re meeting them to commemorate the day in 1841 when a young Herman Melville set out from New Bedford, Massachusetts, on a whaling voyage to the South Pacific that would help inspire his masterwork "Moby-Dick." Today at the New Bedford Whaling Museum, Melville fans will begin a marathon public reading of the novel—an annual event that lasts a leviathan 25 hours.Desktop Version
Field of Light at Sensorio by Bruce Munro
Field of Light at Sensorio by Bruce Munro
Artist Bruce Munro was camping at Uluru (aka Ayers Rock) in Australia in 1992 when he envisioned the art installation on today"s homepage. Titled "Field of Light," it"s currently on display at a venue called Sensorio in Paso Robles, California, the latest stop in a tour of sites around the world. At Sensorio, a new arts center that bills itself as representing "the intersection of art, technology and nature," visitors will find 58,800 solar-powered spheres, lit by optical fibers, that change color. When the sun sets, the fibers illuminate, creating a shimmering, interactive landscape in the meadow. The art installation changes a bit at each site, but Munro tells reporters, "The one constant is that it does make people smile."Desktop Version
